This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

| Get a single character | ${VARNAME[index]} |

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.
As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

So I have been using tmux for a while and have grown to like it and have since added many many customizations to it. Now once you start getting the hang of it, you'll naturally want to do more with the tool.
Now tmux has a concept of window-group and session and if you are like me you'll want multiple session that connects to the same window group instead of a new window group every time.

This is the default case if you simply use the tmux command as your login shell, effectively creating a new group of windows every time you start tmux.
This is less than ideal because, if you are like me, you fire up one-off terminals all the time and you don't want all those one-off jobs to stay running in the background. Plus sometimes you need information fro
